Description

Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from Yellow to green to Blue, relative to the ammonia concentration. No test Kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use. In the absence of free ammonia the unit will assume a Yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a Response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from toxic to safe on removal of ammonia.
